Hi Nicu, I think the best you can do is start with an empty dir, that will give you access to a not layered filesystem, but you need to take in consideration that you will stream data every time that the container restart, so a rolling update can be slow.
My suggestion is to check with you platform team, I know them and I am sure they are happy to help, and understand if the restoration time for the data size you plan is acceptable. Regards.
